Why in one axes can exist two image object?
in [Matlab]

From: Jiang Wen on 20 May 2010 09:35 I use an axes to show a Image(256*176) with the function 'imagesc' and then draw a roi and a line on it. Then I show another Image(208*256) with the function 'imagesc' . I found in the axes there are two image objects, they can be seen at the same time. what's the problem? I only want it show one image one time. How can I delete a image object? Thanks! Jiang Wen

If you want to delete an object that you have the handle to, then use delete(). If you do not have a handle to it, then you can find the handle using findobj().

There's no reason to say "Thou shalt not have two image objects on the same axes at the same time." > what's the problem? I only want it show one image one time. How can I > delete a image object? Thanks! Call IMAGESC with an output argument (the handle of the image object) and DELETE the handle when you want to remove it from the axes. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com
